Embodiment Construction

[0045] The following discussion of embodiments of the invention relating to methods and systems for heating the passenger compartment of a fuel cell powered vehicle is merely exemplary in nature and is not intended to limit the invention or its application and uses.

[0046] As used herein, the term "metal hydride buffer" refers to a solid metal alloy capable of reversibly adsorbing, storing and desorbing hydrogen under pressure. Metal hydride buffers are capable of adsorbing and desorbing hydrogen multiple times without consuming metal alloys. A variety of snubber materials are suitable for use in the metal hydride snubber applications provided herein. In certain embodiments, the metal hydride buffer is composed of a metal alloy selected from the group consisting of cobalt, nickel, copper, and zinc. In another embodiment, an alloy containing iron and lanthanum is suitable for metal hydride snubber applications. In embodiments involving higher desorption temperatures, alumin...

Abstract

A system for conditioning the air in a passenger compartment of a fuel cell-powered vehicle is provided, the system including a metal hydride buffer and a hydrogen source, wherein the metal hydride buffer reversibly adsorbs and desorbs hydrogen gas. The change in temperature associated with adsorption or desorption of the hydrogen gas by the metal hydride buffer is thermally communicated to the passenger compartment, thereby conditioning the air therein. Desorbed hydrogen gas is fed back to the fuel cell to power the vehicle. Also provided are a vehicle having a system for conditioning air in a passenger compartment that employs the change in temperature resulting from the adsorption and desorption of hydrogen gas by the metal hydride buffer and methods for heating or cooling a passenger compartment of a fuel cell-powered vehicle.

Description

technical field [0001] The present invention relates generally to devices for hydrogen fueled vehicles, and more particularly to hydrogen fueled vehicles that use heat generation from the loading and discharge of metal hydride buffers without the use of electrical energy and without oxidation losses of hydrogen to heat the vehicle cabin. Even more particularly, the present invention relates to hydrogen fueled vehicles using a fuel cell system to generate electrical power for vehicle propulsion or for vehicle auxiliary equipment. Background technique [0002] Electrochemical conversion cells, often referred to as fuel cells, generate electricity by processing reactants, such as the oxidation of hydrogen with oxygen in the air. Electric power is provided to an electric motor for vehicle propulsion. The only by-products produced by this system are pure water and heat. This heat is typically dissipated to the environment by means of a liquid coolant circuit and a typical car ...
